摘要
A polyamide acid of the present invention contains, as a diamine component, 2,2-bistrifluoromethylbenzidine and trans-1,4-cyclohexanediamine, and contains, as a tetracarboxylic acid dianhydride component, a pyromellitic acid anhydride and a 3,3,4,4-biphenyltetracarboxylic acid dianhydride. A ratio of the trans-1,4-cyclohexanediamine to a total amount of the diamine is preferably 0.5-40 mol %. A polyimide is obtained by dehydration ring closure of the polyamide acid.
